Diagnostic Trouble Code (DTC) Information BCM-A031
Condition
After the steering wheel angle sensor has been initialized, a check of the plausibility of the steering wheel angle is run.
The diagnostic trouble code (DTC) is stored if the check is not approved and speed exceeds 50 km/h.
The plausibility check can be completed even if BCM-A031 is stored, but before the ignition has been switched off. Diagnostic trouble code (DTC) BCM-0111 is also stored if the check is not completed within one minute.
The diagnostic trouble code (DTC) can be diagnosed at speeds above 50 km/h.
Substitute Value
- Active yaw control is blocked.
Possible Source
- The plausibility check of the steering wheel angle is not approved.
NOTE:
This diagnostic trouble code (DTC) is not due to an internal hardware fault in the Brake control module (BCM) and must not be remedied by replacing the control module.
Fault symptom[s]
- The information lamp is lit
- The stability control system does not function.
